Hi golang-nuts,
I would like to call a C function from Go and get notified about the
execution status in Go, say a goroutine wait until the C function finally
made some progress.
Initially, I thought about passing a channel to C but the cgo document does
not say anything about that:
Later, I a
Thanks for bringing this up. It surprised me too until I realised what was
going on.
The issue here is about the default precision that you're getting for those
big.Float values.
When you use big.NewFloat, the precision you get is exactly the same as
that of a base64 float (53 bits).
When you use

Thanks, I did follow the try proposal and the earlier check/handle

Adding to this:
Generally, comparing FP values for equality can give results you don't
expect due to the way numerics fo
I think there is strong consensus, that the current style of error handling
is currently the best option. Nobody has been able to come up with
something better (really better, not just more comfortable while ignoring
hefty drawbacks).
It is true that a loud minority seems to miss exceptions to

decided to set it free into the wild.
Hare is a pure Go database management system that stores each table as a

I do sometimes do something similar, but without the check() function.
The exit points are explicit, it is guaranteed that errors will be
wrapped.
func do(name string) (err error) {
defer PWrapf(&err, "do(%s)", name)
s, err := works(name);
if err != nil {

Looks very cool! Seems like a nice fit for persistent storage in games

And I will tell you that after working with error returns and exceptions,
exceptions are superior - but much depends on the complexity of the system. For
small system level tools that are pieced together via pipes, C error handling
is fine - because the process serves as the exception handling p

Hi Ian,
Thanks for the hint, but I have some follow-up questions:

Indeed, it the other side will be a spin loop to poll the atomic variable,

Forgot to reply to the list. Oops. Sorry for the second delivery, Changkun.

I changed the encoding so that the previous generated code is no longer
necessary. Encoded data now carries all the information needed to decode
struct fields correctly, even if fields have been added and reordered.
